LazyInitializationException after aop configuration

[mujer_esponja]

Hello, I recently opened a thread here.

I did because I was getting this exception:

4423 [main] ERROR org.hibernate.LazyInitializationException - failed to lazily initialize a collection of role: path.model.listObjects, no session or session was closed
org.hibernate.LazyInitializationException: failed to lazily initialize a collection of role: path.model.listObjects, no session or session was closed

So I tried to set up aop (I think succesfully) in my project, to leave Spring the work to open/close the conections with the database. But after that I am getting the same exception. Could it be another reason for that??

The file where I have set up aop configuration is:

<beans xmlns="http://www.springframework.org/schema/beans"

</bean>


<aop:aspectj-autoproxy proxy-target-class="true"/>

<tx:advice id="txAdvice" transaction-manager="transactionManager">
<tx:attributes>
<tx:method name="*" propagation="REQUIRED" />
</tx:attributes>
</tx:advice>




<aop:config>
<aopointcut id="serviceOperation"
expression="execution(* path.services.**.*(..))" />
<aop:advisor advice-ref="txAdvice" pointcut-ref="serviceOperation" />
</aop:config>

<bean id="ontologyDao" class="path.services.OntologyDao">

<property name="sessionFactory" ref="sessionFactory" />
</bean>

Now the explanation:
path.services is the package where the implementations are
path.services.localImpl is the package where the interfaces are


Thanks in advance
